DETAILED DESCRIPTION OF THE INVENTION

(21) Turning now to the figures, FIG. 1 illustrates a racking system 100 for displaying merchandise. The racking system 100 finds particular use for displaying produce and even more particular use in displaying produce within a refrigerated case 101 (see FIG. 12). The racking system 100 is configurable to tailor the system for displaying varying amounts of product while maintaining the appearance that the racking system 100 is fully stocked with product.

(22) The racking system 100 includes a support frame 102 that supports a plurality of shelves 104, 106, 108, 110 operably mounted thereto. The shelves 104, 106, 108, 110 are vertically spaced apart. While four shelves an illustrated more or fewer shelves may be incorporated into other racking systems.

(23) The shelves 104, 106, 108, 110 are substantially identical except for their front to back depth (e.g. depth between a from end 112 and a rear end 114 as illustrated with reference bottom most shelf 104 in FIG. 2).

(24) The support fame 102 may be mounted in a substantially vertical orientation or in a canted orientation. When mounting in a canted orientation, a spacer bracket 103 (see FIG. 2) may be provided that will push the bottom end of the support frame 102 outward away from any wall to which the support frame 102 is mounted, e.g. a wall 107 of the refrigerated case of FIG. 12 in front of which the racking system 100 is mounted. The spacer bracket 103 is not in use in FIG. 2.

(25) The support frame 102 can include mounting features for mounting. In the illustrated embodiment, the mounting features are in the form of hangers 109. Other embodiments could use pegs, fasteners, etc.

(26) In this embodiment, the shelves 104, 106, 108, 110 are mounted to the support frame 102 in a cantilevered orientation. Optionally, the shelves 104, 106, 108, 110 are vertically adjustable relative to the support frame 102. This allows for adjusting the vertical spacing therebetween to better tailor the racking system for the various products being displayed.

(27) Each shelf 104, 106, 108, 110 has a product support deck (see e.g. product support deck 116 of shelf 104) extending between the front end and rear end of the corresponding shelf. Preferably, the product support deck 116 includes a plurality of apertures 168 formed therethrough.

(28) The product support decks 116 may be mounted such that they slant upward when moving in a from to rear direction, substantially horizontal or with a slight downward slant when moving in the front to rear direction.

(29) To provide for reconfiguration of the racking system 100, a plurality of backing walls 120 are provided. In the illustrated configuration, each shelf 104, 106, 108, 110 includes a plurality of backing walls 120 mounted thereon. In other embodiments, a single backing wall 120 having a width substantially equal to the width of the shelf 104, 106, 108, 110 may be provided.

(30) As the backing walls are generally identical, backing walls 120 on the bottom shelf 104 will be described. The backing wall 120, and particularly a wall portion 122 thereof, extend vertically upward from support deck 116.

(31) The backing walls 120 are adjustably positionable between the front end 112 and rear end 114 of the shelves as illustrated by arrow 126. By adjusting the front to back positioning of the backing walls 120 (e.g. toward or away from the front or rear ends 112, 114), a product display zone 128 above the support deck 116 defined between the from end 112 (and particularly front stop 130) and backing wall 120 (and particularly wall portion 120) can be adjusted.

(32) This allows the product display zone 128 to be tailored to the particular amount of merchandise that will typically be displayed on the particular shelf. This finds particular use for low-volume retailers that want their shelves to appear fully stocked without a large volume of product on the showroom floor. For example, the backing wall 120 can be positioned closer to the front end 112 to reduce the size of the product display zone 128 such that less than the full possible product display zone 128 is exposed.

(33) With reference to shelf 110 and the corresponding backing wall 120, in a preferred embodiment, the wall portion 122 extends at an angle α of between about 90 degrees and 135 degrees (e.g. about 0 degrees and 45 degrees from perfectly vertical when the shelf is horizontal) relative to the product support deck 116. In a preferred, but optional embodiment, the angle α is adjustable.

(34) With reference to FIG. 4, a backing wall 120 is illustrated. The backing wall 120 includes a base 140 that defines a bottom 142 that sits on the product support deck 116 when mounted to shelf 104.

(35) A pair of opposed supports 144 at opposed ends 146, 148 of the wall portion 122. The supports 144 help support the wall portion 122 in an upright position. As used herein, “upright” shall include orientations having a vertical component to its orientation and does not require being perfectly vertically oriented.

(36) With reference to FIG. 5, the wall portion 122 can be formed front a plurality of panel portions 150, 152. Panel portion 150 is attached to and extends laterally between supports 144. Panel portion 152 is adjustably positionable relative to the first panel portion 152 to adjust a vertical height H1 of the back ng wall 120, represented by arrow 154.

(37) In the illustrated embodiment (see also FIG. 9), an attachment arrangement is provided between the panel portions 150, 152. In this embodiment, the attachment arrangement is provided by a forward projecting stud in the form of attachment projection 156 extending forward from a front of panel portion 152 that cooperates with a plurality of apertures 158 formed through panel portion 150. The plurality of apertures 158 are formed in a column and are vertically spaced. As such, the height H1 of the backing wall 120 depends on which aperture in which the attachment projection 156 engages.

(38) With reference to FIG. 9, in some embodiments, the apertures 158 have a central axis 150 extending through panel portion 150 that is not perpendicular to the front surface thereof. In this embodiment, axis 159 extends at a non-perpendicular angle α2 relative to the front surface of panel portion 150. Angle α2 may be, in some embodiments, between zero (0) degrees and 20 degrees. More preferably, angle α2 is at least five (5) degrees. The angle α2 helps secure attachment projection 156 within the aperture 158.

(39) Stud 156 may have an enlarged head that is sized larger than the diameter of aperture 158 to further improve securement.

(40) With additional reference to FIG. 6, the height H2 of panel portion 152 is less than or equal to the height H3 of panel portion 150 such that panel portion 152 can stowed behind panel portion 150 when the backing wall 120 is in its shortest configuration, e.g. as illustrated in FIG. 4. It is noted that attachment projection 156 is used to secure panel portion 152 to panel portion 150 even in this shortest configuration illustrated in FIG. 4. FIG. 5 illustrates the backing wall 120 in its tallest configuration.

(41) Further, width W1 of panel portion 152 is smaller than the width W2 formed between the opposed supports 144. Again, this facilitates stowing the panel portion 152 when the additional height provided thereby is not needed.

(42) With reference to FIGS. 10 and 11, the backing wall 120 defines mounting channels 155 in which the opposed ends 157 of panel portion 152 are received. The panel portion 152 is slideable within the channels 155 when adjusting the position of panel portion 152 relative to panel portion 150.

(43) Panel portion 152 has an outer rim that has a greater thickness than the rest of the panel portion 152. This rim provides increased strength. The thickness is configured for easy sliding motion of the panel portion 152 within channels 155. As illustrated in FIG. 17, live outer rim extends substantially around the entire periphery of panel portion 152, except at tab region 157.

(44) In this embodiment, the channels are formed by laterally inward extending flanges 161 that extend inward from inner surfaces of opposed supports 144. The flanges 161 provide support to the rear of the panel portion 152 and prevent attachment projection 156 from inadvertently disengaging from the desired aperture 158.

(45) In some embodiments, panel portion 152 is flexible such that when the height is desired to be adjusted, the user can flex the middle region of panel portion 152 so that projection 156 does not engage apertures 158. When in the desire position relative to panel portion 150, the user can release the middle region and engage projection 156 with the corresponding aperture 158. The slanted axis 159 helps secure projection 156 in engagement with aperture 158.

(46) In this embodiment, base 140 extends forward of the front surface of wall portion 122 and particularly panel portion 150 forming a front lip 160. In other embodiments, the front lip 160 need not be included. In a preferred embodiment, the top surface of the from lip 160 is parallel to the product support deck 116 of the shelf on which the backing wall 120 is mounted.

(47) With reference to FIGS. 7 and 9, the backing wall 120 includes a plurality of mounting hooks 162 for securing the backing wall 120 to the corresponding shelf and particularly the product support deck thereof. Mounting hook 162 includes a downward extending portion 164 and horizontally extending portion 166. In this embodiment, horizontally extending portion 166 extends in a forward direction relative to downward extending portion 164.

(48) The downward extending portion 164 is generally perpendicular to the bottom of base 140 as well as product support deck 116. However, this is not required. The downward extending portion 164 extends through apertures 168 formed through product support deck 116. The horizontally extending portion 166 extends outward from the downward extending portion 164 and under the product support deck 116.

(49) Preferably, the horizontally extending portion 166 extends a sufficient distance from the downward extending portion 164 such that at least a portion of the horizontally extending portion 166 is offset from aperture 168 when in a mounted state. This is illustrated in FIG. 9 as distal end 170 of horizontally extending portion 166 is offset from aperture 168 and is positioned under a portion of product support deck 116.

(50) With reference to FIG. 7, a downward extending alignment post 172 may be provided to further secure the backing wall 120 to the shelf. With additional reference to FIGS. 10 and 11, the base 140 may include one or more apertures 174 through which the alignment post 172 may extend. This is particularly useful if the alignment post 172 is in the form of a push pin dial provides some engagement with the support deck 116 when inserted through corresponding holes 168 thereof when mounting backing wall 120 thereto.

(51) Push pin 172 may have enlarged head sized larger than apertures 168 to provide increased securement. Alternatively, push pin 172 could be sized larger than apertures 168 to provide a press fit engagement.

(52) To mount the backing wall 120 to the shelf 116, with reference to FIG. 9, the distal end of the mounting hook 162 is inserted through the corresponding aperture 168. The backing wall 120 is then rotated as represented by arrow 176 as the mounting hook 162 is progressively inserted through aperture 168. Once the bottom 142 of the base is testing on the top of product support deck 116, the optional push pin may be inserted through aperture 174 (FIGS. 10 and 11—pin not shown).

(53) Preferably horizontally extending portion 166 extends forward, e.g. towards from end 112 of shelf 104. As such, if product pushes against the front surface of wall portion 122 applying a rearward directed force (see e.g. arrow 180 in FIG. 9), the forward extending portion 166 will push against the bottom of the product support deck 116. Thus, the horizontally extending portion 166 should be sized such that the horizontally extending portion 166 is, at least in part, offset from aperture 168 when mounted.

(54) Due to the inclusion of a plurality of apertures 168 spaced both front to back as well as side to side in the product support deck 116, the position of the hacking wall 120 can be both adjusted front-to-back as well as side-to-side relative to the shelf.

(55) Because the racking system 100 finds particular use in refrigerated cases, the backing walls 120 include a plurality of apertures 182 formed therein. The apertures 182 allow cooled air or mist to pass therethrough to allow for proper climate control

(56) In this embodiment, the apertures 182 are arranged in two separate arrays that are separated by the column of apertures 158 for securing the first and second panel portions 150, 152. In this embodiment, the apertures 82 have a larger diameter than the diameter of apertures 158. However, this is not necessary.

(57) Further, it is desired that the pattern of the apertures 182 is such that the pattern is consistent when transitioning between panel portion 150 and 152 so that it reduces the visual appearance that multiple panel portions are used. As illustrated in FIG. 5, the incremental vertical adjustability of panel portion 152 relative to panel portion 150 is directly correlated to the vertical spacing of the horizontal rows formed by apertures 182 (e.g. apertures 158 directly align with corresponding rows formed by apertures 182).

(58) The backing wall 120 may be adjustable between a vertical height H1 of between 5 and 15 inches and preferably between 6 and 10 inches. The backing wall 120 are preferably configured such that they extend vertically between two vertically adjacent shelves at least 90 percent of the spacing between the vertically adjacent shelves (e.g. the vertical spacing between shelves 104 and 106).

(59) With reference to FIGS. 5 and 13, panel portion 152 includes knockout regions 188 that are designed to be easily removed from the remainder of the panel portion 152 to accommodate shelf brackets 102 that support the product support deck of the shelf vertically above the corresponding backing wall. For example, the knockout regions 188 could be bound by perforations, scores, creases, etc. to differentiate them from the remainder of the panel portion 152. Arrow 194 illustrates a region where a knockout region 188 has been removed from panel portion 152. The knockout regions 188 have been removed for shelves 104, 106, 108 in FIG. 3.

(60) The backing wall 120 is easily removable for cleaning as well as easy display reconfiguration.

(61) Preferably, the surfaces of the racking system 100 exposed to and or come into contact with the displayed product contain anti-microbial additives.

(62) FIG. 15 illustrates a further embodiment of a racking system 200 that is similar in many respects to racking system 100. Only the differences therein will be described. All of the features of racking system 100 described above are equally applicable to racking system 200.

(63) In this embodiment, dividers 202 are provided. The dividers 202 extend forward of the front of the wall portion 122 of the backing wall 120, at least in part. The dividers 202 separate the product display zone 128 forward of the backing wall 120 and rear word of the front 112 of the shelf into separate display zones 128 for a single shelf.

(64) In this embodiment, the dividers 202 have a main divider body 204 that is generally vertically oriented and generally orthogonal to support deck 116. The dividers 202 also include mounting feet 206 that extend laterally outward from the main divider body 204.

(65) Preferably, one mounting foot 206 is positioned in front of the backing wall 120, e.g. proximate a front end 112 of the shelf (see FIG. 16) while a second mounting foot 206 is positioned behind the backing wall 120, e.g. proximate a rear end 114 of the shelf (see FIG. 17).

(66) With reference to FIG. 18, the divider 202 preferably includes mounting pins 210 that extend downward from a bottom 212 of the divider 202. The mounting pins 210 extend into apertures 168 in the support deck 116. Preferably, the mounting pins 210 are radially flexible to provide an increased friction fit engagement with the support deck 116 when inserted into apertures 168.

(67) The mounting pins 210 of this embodiment or integrally molded with the rest of divider 202. However, separate push pins could be provided.

(68) Mounting pins 210 have a pair of legs 230 that are separated by a gap 232. The legs 230 are connected at ends thereof. The spacing of legs 230 allows for them to be resiliency biased towards one another when mounting the divider to the support deck 116.

(69) Other mounting or push pins discussed above could have a similar design, e.g. structure 172 of the backing wall 120.

(70) Preferably, the spacing S1 between the mounting feet 206 (FIG. 18) is greater than the depth D1 of the base 140 of the backing wall 120 (FIG. 16). With reference to FIG. 6, the difference between spacing S1 and depth D1 provides adjustment region 216 that allows for forward and backward adjustment of the position of backing wall 120 without the feet 206 interfering with mounting of backing wall 120 to support deck 116.

(71) The backing walls 120 have a width that is sufficient to provide a gap 240 through which the main divider body 204 passes. Each backing wall 120 on opposed sides of the divider 202 is independently adjustable in the forward and backward direction (e.g. illustrated by arrow 126).

(72) FIG. 17 illustrates a further feature of panel portion 152. In this panel portion, a pair of slits 153 separate a tab region 157 that carries attachment projection 156 (see FIG. 16). The slights weaken the portion of the panel portion 152 from which the attachment projection 156 projects to allow for easier disengagement and engagement of the attachment projection with apertures 158.
